One place to look for this information is the "Rehab the Lab" web site hosted by the King County, Washington's Local Hazardous Waste Management Program. See
https://urldefense.proofpoint.com/v2/url?u=http-3A__www.hazwastehelp.org_educators_rehabthelab.aspx&d=BQIFAg&c=lb62iw4YL4RFalcE2hQUQealT9-RXrryqt9KZX2qu2s&r=meWM1Buqv4IQ27AlK1OJRjcQl09S1Zta6YXKalY_Io0&m=aKRuyu_k0fu9pkiNSPNeVuGhBzTuLgliJLx4NxgiNAc&s=DnRQU3F9Xeo9S9_Wh72J6uOih78KRZm6bfyc2wHS4v8&e=
Included on this site is a database of about 1000 chemicals that have been found in high school labs over the last 20 years, what they might have been used for, and an opinion from a group of science educators as to what grade level they appropriate to use for. Lead Nitrate is listed as "high school" for lowest grade level and "lead iodide" isn't listed, although "Lead Diiodide" is as "High school w/ chemical hygiene officer approval".
Perhaps this information is helpful.
